Patented Oct. 8, 1945 w UNITED STATE s PATENT OFF c WINDOW oonsrrauoirron Rodney Dawes, Royal Oak, Mich. Application November a 194-3, Serial No. 509,001 20 Claims. (01. 1 0-188) This invention relates to window constructions, and more particularly to the plurality of sashes adapted to vertical adjustments within the window frame, as well as outward tilting movement therein. v

It is the object of the present invention to provide a two sash window centrally hinged and adapted to outward swinging movement on opening movement of either or both sashes.

It is the object of this invention to provide a double hinged window construction with manually operable window regulating means adapted to cause upward movement of the lower hinged sash throughout the entire length of the window opening, with type embodying a the upper portion merely pivoting -window adjusting means,

outwardly, whereby the two sash members are 7 brought into parallel horizontal relationship at the top of the window frame.

It is the further object to provide a window construction with means permitting dropping of the upper sash pivotal support throughout the entire length of the window frame until the .two sashes have assumed a parallel horizontalposition at the bottom of the window frame, and with their common hinge being outwardly projected therefrom.

It is the further object herein to provide manually operable means for causing upward translation of the two parallelfolded horizontal sashes from the bottom of the frameto the top thereof; or from the'top thereof to the bottom. u It is the further object of this invention to arrange the Weatherstripping of the intermediate hinged portions of the two sashes as well as at the bottom of the lower sash whereby on nominal releasing movement of the manual regulating means said central hinged portion will initially snap outwardly sufiiciently to prevent binding of the window sashes upon further manual 'regulae tion.

It is the further object .herein to provide manual .regulating means for causing raising and lowering of the pivotal bottom support of lower sash, as well as separately operablemanual regulating means causing lowering and raising of the top pivotal support of the upper sash; it

being understood that the'central hinged portion of the window is at all times adapted to outward translation upon movement of either or both of said sashes. I

It is the still further object herein to provide a window frame construction with vertical slotted sections for housing threaded, rotatable window adjusting means, together with correspondingly threaded cooperating support and guide means slidably disposed through said slotted portions and pivotally joinedto the lower portions of the lower window sash, whereby on rotation of said adjusting means, said window support may be raised or lowered. At the same time the upper supports for the upper window sash pivoted thereto .are' slidingly and guidingly disposed through the slotted portions of said vertical sections.

It is the further object herein to provide a right handed thread at the lower ends of the V and left handed threads at the upper end portions of said means whereby the upper and lower portions of the two windows are adapted for vertical adjustment towards and away from each other.

It is the still further object herein to provide -,a similar construction employing a hollow I of the upper sash.

, which:

These and other objects will be seen in the following specification and claims wherein the present invention is seen to reside in the various combinations of elements and arrangements thereof, as illustrated in the accompanying drawingsof Fig. ,1 is a partially sectioned side elevational view of the window construction.

thereof view of a slightly different type of window construction.

Fig. 7 is a fragmentary side elevational section of the upper window adjustable support h wn n Fi 6.

It willbe understood that. the above drawings are merely illustrations of preferable embodiments of the present invention and that other embodiments are: contemplated within the scope of" the invention as set out in the appended claims.

Referring to the drawings Figs. 1, 2 and Show the hollow rectangular frame I with the longitudinal sill 2 prov ded intermediate the ends vided within frame I as shown in Fig. 4, being nested and-suitably secured against the vertical members of frame I, with said slotted portions facing the outside of the frame.

As shown in Figs. 1 through 4 shafts II and I2 respectively threaded at I3 and I4 and provisioned centrally within channel members 8 and 9 are suitably supported therein, having annular collars I5 at their lower ends for rotatable support upon bearings I6 within sill 2. The upper endsof vertical shafts II and I2 are rotatably journaled within bearings I! in of frame I.

Bevel gears it and I9 keyed on the lower ends of shafts Ii and i2 the two bevel gears and'ZI keyed on opposite ends of horizontal shaft 22 which is rotatably supported by the two brackets 23 and 24 de ending below sill 2.

As'shown in Figs. 1 and 2 brackets 25- and 25 depending-centrally below sill 2 provide a journal and support for the manually rotatable window regulator 27 with shaft 28. Worm gear 29 keyed on shaft 23 operatively and threadably meshes with gear 3i] keyed on horizontal shaft 22, wherei by rotation of regulator 2? will cause rotation of shaft 22 and rotation of shafts'II and i 2 geared thereto. 3

Dogs 3| and 32 shown in Figs, 1 and 3 pivotally hinged at 33 within notches 3:1 in the bottom of sash 3 are in threaded engagement at 35 and 36 withthe respective vertical rotatable shafts II and I2 and their threaded portions I3 and I4.

On the other hand dogs 31 and 38 shown in Figs. 1, '2 and 5 pivotally hinged at 39 at the top edge of upper sash 6 hav laterally flanged guide portions 45 on the ends thereof for cooperative sliding engagement against the inner surface of channel members 8 and 9 within frame I.

Guides 40 are normallyretained slightly belowtheir extreme upper position by the -transverse pins 4i slida-bl through frame I and channel members 8 and 5. Pins 4| with handles 42 have annular collars 53 engaged by coiled springs 44 within spring housings 45 which springtends to resist withdrawing of said pins partiallyfrom frame I but allows sufficient withdrawal to permit dogs 3'! and 38 to be free to drop within channel members 8 and 9.

Thus a sliding pivotal support is provided for the upper part of sash 5, which is adapted for guided sliding vertical adjustment through dogs 3! and 38 within slotted channels 8 and 9; With the amount of friction previously ascertained between flanged portions 40 of dogs 37 and 33 and slotted channels 8 and downward movement of sash merely by applying a minimum mitting gravity to do the rest.

With sashes 3 and 5 pivotally centrally at 5 manual rotation of regulator 2'! in one direction effecting rotation of shafts II and I2 will cause dogs 3I and 32 to ride upwardly upon their threaded connections so that the lower ends of sash 3 will travel upwardly while the hinged portions 5 of both sashes 3 and 6 will progressively project outwardly.

By continual rotation of handle 27 it is possible to cause sash 3 to rideup the full height of window frame I, with the result that both sashes 3 6 when released of force and perthe top member are in operative mesh with N 9 it is possible to effect 4 and 6 will be in horizontal and in parallel relation at the top of the frame. By rotating handle 27 in the opposite direction it is seen that both sashes will be closed to the position shown in Fig. 2.

However at elevated horizontal position of both sashes at the top of frame I, pins II may be manually withdrawn sufficiently against springs 44 to release the upper pivotal supports of sash 6, whereby upon opposite rotation of handle 2'! sash 3 is operatively lowered in horizontal position, with upper sash 6 horizontally resting thereon and also riding downwardly. Thus both sashes may be brought down while remaining in horizontal parallel relation to the sill 2 near the bottom of frame I. In this position the outside surface of glass I of upper sash 6 may be easily washed. While in the extreme upward horizontal positions or intermediat horizontal positions of sashes 3 and E the outside of glass 4 in the lower sash can be easily washed.

It is contemplated that lower do attachments 35 and 36 may have projections 35 as in Fig. 2 for operative engagement with the ends of pins ll angularly shaped at M, for causing releasing movement to the right on engagement therewith, at the same time permitting release of upper dog guides 40, permitting downward movement thereof.

Without actuation of handle 21 upper sash 6 may be lowered merely by manually releasing pins 4! permitting dogs 3'! and 38 toguidingly slide downwardly to any intermediate position along window frame I. It is seen that any downward movement of sash 5 causes at least outward movement of the hinged portion 5 of the two sashes, even though'the lower portion of the lower sash remains stationary.

Weatherstripping 46 and 4'! is provided upon the'bottom edges respectively of sashes 6 and 3, and are so provided that a slight releasing movement of handle 21 will permit the central hinged portion 5 to snap outwardly sufficiently to prevent any binding of the sashes against each other upon further actuation of handle 21. By this pop out? action it is clear that any of the adjustments of the sashes above described are possible without any binding. I

In fully closed position of the window as in Fig. 2, upper sash 3 rests upon lower sash 3. However in the initial pop out position above, upper dog members 33 and 39 drop down slightly to rest upon pins 4|.

While the above description shows means releasing the upper sash to be free falling subject to a certain amount of desired sliding friction, it is contemplated that dogs 37 and 38 may be in threaded ed portions oppositely threaded in direction from threaded portions I3 and I4, as shown in Fig. '7. Thus on rotation of regulator 21 in one direction, dogs 31 and 33 on sash 5 and dogs 3t and 32 on sash 3 would approach each other with the result that both sashes would be in horizontal parallel positions at the center of the frame opening. Rotation of regulator 2'! in the opposite direction would cause dogs 37 and 38, and 3| and 32 to move in threaded engagement with shafts II and I2, but away from each other to intermediate positions or to the closed position of Fig. 2.

It is contemplated however that it may be desirable to open sashes 3 and 6 in unequal amounts, and to accomplish this a slightly different construction is shown in Figs. 6 and 7.

Within the hollow channel sections 8 and 9 engagement with corresponding thread- I l for pivotal attachm by an. interme slotted atv 1.0 are provided the hollow threaded rotatable'shafts 4.8 and 49, threadably engaged by the interiorly threaded. portions 5!) and 5l of corresponding dogs .52 and 53. Said dogs slidably project through slots in and: are adapted out .to the lower end of the lower window sash 3 in the :manner illustrated inFigl. J. :Shafts Hand dfirotatably carried and journaledby bearings 5-4 in sill 2 have bevel gears .55 and 56. on their ends in operative engagement with ibevelgears. 5 and 58 on the ends of rotatable shaft 59. Shaft .59 journaled by brackets (it; and BI depending'below sill 2 .carries gear 62 mesh with rotatable spiral gear 53. The latter is rotatably carried by manually rotatable shaft 64 and a suitable handle, not shown, supported by bracket 65; or a pair of such brackets depending from sil1 2 in a manner similar to brackets 25, and 26 shown in Fig. 1.

Thus rotation of regulator shaft 64 causesrotation of horizontal bar 59- and vertical hollow threaded shafts 8 and 49, effecting vertical adjustments of the corresponding dogs 52' and 53 securedv to the lower window sash. Raising and lowering of the lower sash is thus accomplished byv manual rotation of regulator shaft 6d.

Within hollow threaded shafts 48 and 49 are rotatably disposed the oppositely threaded shafts E5 and fifi journaled at 81 within the top portion of frame 5 and withtheir annular collar portions '68: at the lower end providing a supporting journal with respect to brackets 69 secured to frame I, below sill 2.

Rotatab'le shafts 65 and 66 have bevel gears 10 and 'M adjacent their ends mesh with corresponding bevel gears 12 and 13, on shaft M, also rotatably journaled through the supporting brackets Hand 6! below sill 2.

Shaft l4 carries gear 15 in mesh with rotatable spiral gear 15 on rotatable regulator shaft 11 journal'ed and. supported by bracket 18 or a pair of such brackets similar to the brackets 25 and'ZB shown in Fig. l.

"Ihus rotation of rotation of'bar M an 65 and 66, effecting v corresponding threaded portion dogs Bl and82-.

Dogs 8i and 82;

regulator shaft 11 causes d vertical threaded shafts ertical adjustments of the s 19 and 80 on slidably projecting through slots in hollow sections 8 and 9 pivotally support at 83 the upper portions of upper sash 6 as shown in Fig. '7. Thus vertical adjustments of upper sash 6 are effected by regulator shaft H independently of the vertical adjustments of lower sash 3 through it is contemplated however that both sashes 3 and are similarly hinged centrally and that said hinged portion projects outwardly upon the vertical adjustment of either or both of sashes 3 and 6.

It will be unders described is also adapt tood that the invention above able to door constructions wherein the door consists of two or more panels centrally hinged, together with means for causing vertical adjustments thereof.
